Multiple realities(covers information from several alternate timelines)
The Gagarin Radiation Belt was an area of space that surrounded the Loracus system.
At one time, the radiation belt made travel to this system all but impossible until the system's primary star became relatively stable prior to 2151. (ENT: "Strange New World")
In 2164, the Federation starship USS Franklin went missing in the belt. (Star Trek Beyond)
It was later theorized in 2263 of the alternate reality by Montgomery Scott that the ship experienced a wormhole displacement to account for its remote distance, for the 22nd century, from Earth after the ship was discovered on the planet Altamid. (Star Trek Beyond)
The Gagarin Radiation Belt was possibly named after Yuri Gagarin, the first Human ever to venture into space by completing a full orbit of Earth in 1961.
